4.7.1 acec start (Synchronous High-speed Copy Start Command)

NAME

acec start - Start of synchronous high-speed copying

SYNOPSIS

When Copy Type Set in Copy Group Is EC

acec start -g copyGroup [-p copyPair] [-r] [-da] [-xml]

When Copy Type Set in Copy Group Is REC

acec start -g copyGroup [-p copyPair] [-r] [-transfer {sync [-split {auto | manual}] | through | consist | stack}] [-recovery {auto | manual}] [-skip] [-da] [-xml]

DESCRIPTION

This command starts synchronous processing for the synchronous high-speed copy for the specified copy group or copy pair.

OPTIONS

-g copyGroup: This option specifies the copy group name.

-p copyPair: This option specifies a copy pair.

-r: This option performs a copy in the reverse direction to the direction that has been specified.

-transfer {sync [-split {auto | manual}] | through | consist | stack}

This option specifies the transfer mode. (Only for REC)
The default mode is "stack". Refer to "3.2.2.5 REC Operating Modes" for information on each mode.

sync: Synchronous mode
This option specifies the split mode when sync was specified with the -transfer option (Only for REC)
-split
The default mode is "auto".
- auto: Automatic Split
- manual: Manual Split
through: Through mode
When the storage device is registered to operate by Copy command via LAN, this transfer mode cannot be specified.
consist: Consistency mode
stack: Stack mode

-recovery {auto | manual}

This option specifies the recovery mode. (Only for REC)
The default mode is "auto". Refer to "3.2.2.5 REC Operating Modes" for information on each mode.

auto: Automatic Recovery
manual: Manual Recovery

-skip: This option specifies when the synchronous process is suspended by using the initial copy skip function.
This option can be specified when the synchronous high-speed copy for inter-box is started.

-da

From the start of the EC/REC synchronous high-speed copy process until its suspension, always set the copy destination logical volume to unreadable.

It is not possible to use this option if one registered the device as a device which is operated by Copy command via SAN and moreover has specified "through" with the -transfer option.

-xml: This option specifies when displaying the result of the command execution by the XML format.

EXIT STATUS

=0: Completed successfully
>0: Terminated abnormally

NOTES

When the copy type of copy group is OPC, QuickOPC or SnapOPCP, this command cannot be executed.
This command terminates abnormally if the copy destination logical volume of the specified copy group or pair is protected by the acinhibit set command.
